Broad-tailed Hummingbird
Selasphorus platycercus
Common hummingbird of high elevations. Breeds in open woodland with meadows and scrub. In winter, found at lower elevations. Male is distinctive in range with beautiful rosy-red throat and glistening green upperparts. Female is duller with buffy sides and speckled throat. Note broadly rounded tail feathers with restricted rufous. Feeds on nectar and small insects. Visits feeders.
Identification
Medium in size, the broad-tailed hummingbird is 4 inches (10 cm) in length and possesses an overall wingspan of 5.25 inches (13.3 cm). Weighing around 3.6 grams (0.13 oz), the female tends to be slightly larger than the male. Adults of both sexes show an iridescent green back, white eye ring and a rounded black tail projecting beyond their wing tips, from which their name was inspired. <p>This species shows sexual dimorphism, which means that male and female have different characteristics. The male possesses a characteristic bright rose-red gorget. An identification characteristic is the white eye ring. The female can be distinguished from the male by her paler coloration, cinnamon flanks, and spotted cheeks absent in the male.<p>The broad-tailed hummingbird produces several different sound patterns. This bird's call sounds like a sharp “cheet”, which is repeated “cheet cheet cheet cheet...”. Hummingbird wing beats have also been found to be a communication signal. These birds produce two different types of sound using their wing beat. The first one is a “wing hum” and is simply produced when the hummingbird flies. This type of wing beat has a sound that ranges from 35 to 100 Hz, and both sexes are able to produce it for communication. The second is “wing trills” produced by the male hummingbird during courtship displays. The wing trill produces a buzzing sound and can be heard 50 m away by other males and 75 m away by other females. This sound is produced when air passes rapidly through the 9th and 10th primary feathers. In one experiment, birds without this wing trill lost their territory more easily to more aggressive birds.
Taxonomy
The broad-tailed hummingbird, Selasphorus platycercus, is a member of the order Apodiformes, in the family Trochilidae. Hummingbird taxonomy has not been extensively studied, but its phylogenic division can be divided as a family into nine clades in which the broad-tailed hummingbird is a member of the "Bee group" and included in the Selasphorus genus. This genus is composed of 6 members taxonomically distinguished based on color characteristics. This genus is characterized by hummingbirds with a plumage containing rufous coloration and a neck gorget of orange to purple in males.<p>Members of this genus include:<p>Selasphorus sasin : Allen's hummingbird<p>Selasphorus rufus : Rufous hummingbird<p>Selasphorus scintilla : Scintillant hummingbird<p>Selasphorus ardens : Glow-throated hummingbird<p>Selasphorus flammula :Volcano hummingbird<p>On a geographic scale, the genus Selasphorus can be subdivided into 2 groups of species, one living in North America, and a second in the region of Costa Rica and Panama.

Range and habitat
The broad-tailed hummingbird is found from Guatemala to Mexico, and western United States and Western Canada during summer, while wintering regions are mainly in southern Mexico and Guatemala.<p>This species exhibits partial migration, depending on the northern range during winter. The specific migratory route used by the broad-tailed hummingbird remains unknown, although migrating populations winter in southern Mexico or Guatemala and return to their breeding area in spring. Males arrive first to the breeding range, followed by breeding females. Some populations of the broad-tailed hummingbird in southern Mexico and Guatemala do not migrate, a variation in behavior called "sedentary". This hummingbird is seen in the understory or under tree canopies of pine and oak woodland. It forages in open areas with flowers or in grasslands among trees and shrubs. Its breeding habitat is mainly in subalpine meadows, foothills, montane valleys, and stands of aspen or spruce.

Conservation
This species conservation status is “Least Concern ”, indicating it is not an endangered species, having a wide range and moderate population size, although one survey indicated a 52% decline in population between 1966 and 2015. It appears to be adapted to human-modified habitats.

Other Birds
Dusky Robin
Melanodryas vittata
Medium-sized, rather long-tailed Australian robin, both sexes plain brown overall. Darker than similar species and lacking any pale wing panels. Often perches on a rock or stump, from which it pounces on prey on the ground. Endemic to Tasmania, where inhabits open forests, gardens, and coastal heathland.
Maxwell's Black Weaver
Ploceus albinucha
An entirely black forest weaver with piercing white eyes found in low-elevation and foothill forests, in small groups or with mixed-species flocks, sometimes with other species of weaver. Occasionally forms much larger groups, and will sometimes nest in large single-species or mixed-species colonies. Birds in the western part of the range have a silver nape, but birds in the east are wholly black. Western populations are nearly identical to co-occurring populations of Vieillot’s Weaver, but have a thinner, pointier bill and prefer more forested habitats. Vocalizations include dry chatters and soft mechanical rasps, sometimes given in complex combinations.
Pied Honeyeater
Certhionyx variegatus
Medium-sized honeyeater with long decurved bill, nomadic across arid and semi-arid inland Australia. Male black with white belly, wing patches, and tail panels; distinctive patch of blue skin beneath eye. Female and juvenile plain brown, with subtly patterned wings and faint speckles on chest. This species wanders in search of flowering shrubs and can be absent one year, common in large flocks the next. Much larger than Black Honeyeater (which has completely black upperparts). Calls include a slowly whistled phrase of several notes.
